1-recommend any TWO temporary dewatering methods to lower the ground water table which are best suitable to given situations of the construction site.
i. Calculate the output of the360° excavator per week, assuming a normal working week of 40 hours which includes down time of 10 minutes in every hour.
ii. Determine the ‘Plant Team’ and ‘Number of Weeks’ required for the removal of 10000m3 of soil.
i. Determine minimum number of passes and minimum depth of compacted layer in mm.
ii. Determine the volume of soil handled per week by this Vibrating Roller based on limitations and capabilities provided.
i. Determine allowable pile load, Using Skempton's formula. (10 marks)Where, α = Adhesion factor (assume 0.48 for clay) and Factor of safety as 2.5
ii. Determine the diameter of the pile (200mm - 400mm), actual length (8m – 20m) and effective length (10m – 20m) of a pile to cover the applied load. (5 mar
